Shade of Yin

Yin has broken off a portion of their strength to inhabit a humanoid creature's body, providing the following benefits:
• Dark Empowerment. Each of your ability scores and their maximums increase by 2.
• Darkened Form. You gain resistance to radiant and necrotic damage, as well as nonmagical bludgeoning, piercing, and slashing damage. If you are already resistant, you instead gain immunity to these damage types.
• Darkest Sight. You gain darkvision out to a range of 60 feet and can see through magical darkness. If you already have darkvision, its range increases by 60 feet.
• Desecrating Darkness. Your weapon attacks are considered magical. When you hit with with any weapon, it deals an extra 1d8 necrotic damage. If you are dragonborn, your breath weapon gains a necrotic damage dice pool in addition to its normal damage, which scales with your breath weapon's normal damage.
• Evil Eyes. You have advantage on Charisma (Intimidation) checks.
• Shadowy Speed. Your movement speed is doubled. In addition, while you are in dim light or darkness, you can hide as a bonus action.
